    摘要： (.+-.)4-demethoxy-6(and-11-)-deoxydaunomycinone which are starting materials for anthracycline antitumor antibiotics are prepared by reacting 1,2,3,6-tetrahydrophthalic anhydride with an alcohol of the formula ROH, wherein R is lower alkyl, substituted lower alkyl or aryl to form a monoester, subjecting the monoester to a Friedel-Crafts reaction with acetyl chloride, followed by mild alkaline treatment, to give the corresponding .alpha.,.beta. unsaturated ketone, catalytically reducing same to form the corresponding 4-acetyl-perhydrophthalate reacting the latter with 1,4-dimethoxynaphthalone in the presence of tritluoroacetic anhydride and trifluoroacetic acid to form a mixture of two isomeric compounds, submitting said mixture of isomers to a catalytic reduction of the benzylic carbonyl function, followed by treatment thereof with sulphuric acid at room temperature to afford a mixture of tetracyclic isomers, treating the mixture of tetracyclic isomers with sulphuric acid at 80.degree. C. for one hour to give a 1:1 mixture of the racemic anthracyclinones above mentioned.

    摘要： Disclosed is a process for preparing the glycoside antitumor anthracyclines 7-0-(2,6-dideoxy-.alpha.-L-arabino-hexopyranosyl)-daunomycinone (Ia); 4-demethoxy-7-0-(2,6-dideoxy-.alpha.-L-arabino-hexopyranosyl)-daunomycinone (Ib); 7-0-(2,6-dideoxy-.alpha.-L-arabino-hexopyranosyl)-adriamycinone (Ic); 4-demethoxy-7-0-(2,6-dideoxy-.alpha.-L-arabino-hexopyranosyl)-adriamycinone (Id); 7-0-(2,3,6-trideoxy-.alpha.-L-erythro-hex-2-enopyranosyl)-daunomycinone (IIa); 4-demethoxy-7-0-(2,3,6-trideoxy-.alpha.-L-erythro-hex-2-enopyranosyl)-daunomycinone (IIb); 7-0-(2,3,6-trideoxy-.alpha.-L-erythro-hex-2-enopyranosyl)-adriamycinone (IIc); and 4-demethoxy-7-0-(2,3,6-trideoxy-.alpha.-L-erythro-hex-2-enopyranosyl)-adriamycinone (IId). Compounds Ia, Ib, IIa, IIb are prepared by condensing daunomycinone and 4-demethoxydaunomycinone with 3,4-di-0-acetyl-2,6-dideoxy-.alpha.-L-arabino-hexopyranosyl chloride in an inert solvent in the presence of silver triflate (silver trifluoromethansulfonate), as catalyst, and by removing the protecting groups. Analogously the derivatives Ic, Id, IIc and IId are prepared by condensing a novel reactive protected derivative of adriamycinone and 4-demethoxyadriamycinone in the presence of mercuric bromide/mercuric oxide with the above mentioned sugar halide. The new compounds of the invention are useful in treating certain tumors in mammals.

    摘要： [14-.sup.14 C]-daunorubicin and doxorubicin are prepared by reacting 9-desacetyl-9-formyl-N-trifluoroacetyl daunorubicin with [.sup.14 C]-diazomethane to form [14-.sup.14 C]-N-trifluoroacetyl daunorubicin from which the protecting group is removed by mild alkaline hydrolysis to afford [14-.sup.14 C]-daunorubicin which is then, in the form of the hydrochloride, reacted with bromine to form the corresponding labelled 14-bromo derivative, which, upon treatment with sodium formate leads to [14-.sup.14 C]-doxorubicin.
